Looking for some BUILDERS to teach / guide me

Sorry to miss the live event ! As output size is unchanged I have to think that MINIMAL_APPS was not applied ?

Yes you do, otherwise nothing with a EOS_ can happen.

Did your /e/ build rewrite your device.xml with a roomservice.xml, if yes we can say that is a good manifest – then two more projects in your proposed build:

<!-- vendor extendrom
    ##################################################### -->
  <remote name="sfX" fetch="https://github.com/sfX-Android/" />
  <project path="vendor/extendrom" name="android_vendor_extendrom" remote="sfX" revision="main" />
<!-- /e/ vendor repo
    ##################################################### -->
  <project path="vendor/e" name="steadfasterX/android_vendor_e" remote="e" revision="v1-r" />

It was as I was learning to set up vendor_e properly that I depended on envsetup.txt and breakfast output to see that my environment was correct. My last envset.txt https://paste.tchncs.de/upload/falcon-crow-eagle

(Unexplained, but I found that you should get the environment right before you call envset.txt)

I find you have to be fussy with consistent use of “quote marks” for variables.

Interesting footnote envsetup.txt confirms the use of

ANDROID_JACK_VM_ARGS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx9G"

On your machine I would start at 5G (the default in your OS may be 2G insufficient)

I never edited that, the readme at that location explains better than me !
